I've noticed a lot of people who, according to the way I was taught, misuse the words 'worse' and 'worst'. The way I understand it, 'worse' is for comparisons, and 'worst' is the superlative. But more and more I see people using them in the exact opposite positions.
That's the worse thing I've ever seen.
This can't get any worst.
This specific thing seems to occur a lot more than any mistakes, so I'm wondering what's up with this.

You are right — they are definitely misusing worse and worst in those examples.
However, I think the impression that this error is catching on may be an illusion — the usage isn't really changing, it's just such a jarring mistake that when you meet it, it really stands out. Googling the phrases you mention, compared with their correct versions, gives:
Google hits are an awfully rough measure, but these differences — factors of around a hundred in each case — show pretty conclusively that this isn't a common usage. If anything, for words that are so close together in both pronunciation and spelling, I'm surprised there aren't more people making this mistake as a typo or thinko.
